Question

Chloe drives from her house to her grandma's house 64 miles away in an hour and 35 minutes. How fast was she driving on average? About 47 mph About 53 mph About 40 mph About 30 mph

Answer 1

About 40 miles per hour

Answer 2

She was driving at 40.42 mph on average

Explanation:

In this exercise, for us to find the speed that Chloe drives with we need to first convert the time she spent driving to hours completely since the time given is in hours and minute

Data

distance= 64 mile

time= 1hr 35min

to covert 1 hr 35 min to hours we have

= 1 + 35/60 (we are converting 35 min to hrs)

= 1+0.583

= 1.583

hence speed= 64/ 1.583

speed= 40.42 mph

She was driving at 40.42 mph on average
