Khaya is delivering groceries to his mother who stays 8km from the shop. How long will it take him to cover this distance if he drives at an average speed of 65km/h? Give your answer rounded to the nearest minute.

7.38 minutes

Step-by-step explanation:

Given

Distance= 8km

speed = 65km/h

Time=?

From physics,

Speed= distance/ time

Then substitute the values to find time

65= 8/ time

Time= 8/65

=0.1231 hrs

To Convert to minutes

1hr= 60 mins

0.1231 hrs = X minutes

Cross multiply, we have

X minutes=( 0.1231 × 60)/1

= 7.38 minutes

Hence, it takes 7.38 minutes for him to cover this distance

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
