A bicycle is traveling at 20 miles per hour. How many feet will it cover in 55 seconds?
Round your answer to the nearest tenth of a foot.

Step-by-step explanation:

Given the conversion 1mile = 5280feet

If a bicycle is traveling at 20 miles per hour, then the bicycke must have been travelling at (20*5280)feet per hour which is equivalent to 105,600 feet per hour.

To know the number of feet that will be covered in 55seconds, we will solve the equality operation;

If 105,600 feet  = 1hour (3600secs)

x foot = 55secs

where x is the amount of feet it will cover in 55 seconds?

Cross multiply

3600 * x = 105,600*55

3600x = 5,808,000

divide both sides by 3600

3600x/3600 = 5,808,000/3600

x = 1613.3 feet (to the nearest tenth)

Hence the amount of feet covered in 55seconds to the nearest tenth is 1613.3 feet

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
