Alejandra drove from michigan to colorado to visit her friend. the speed limit on the highway is 70 miles/hour. if alejandra combined driving time the trip was 14 hours, how many miles alejandra drive?

The distance cover by Alejandra to travel from Michigan to Colorado is 980 miles

Step-by-step explanation:

The speed Limit on the High way = 70  mile per hour

The time taken = 14 hours

Let the distance cover from Michigan to Colorado = x mile

SO , Formula

Distance = Speed × Time

Distance = 70 mile per hour × 14

So, Distance = 980 miles  

Hence  The distance cover by Alejandra to travel from Michigan to Colorado is 980 miles      Answer

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
