Question

Dewey rides his bicycle 2 miles in 0.20 of an hour. At this rate, how many miles can he ride his bicycle in 5 hours?

a) 10 miles
b) 20 miles
c) 12.5 miles
d) 25 miles

Answer 1

Dewey rides at a rate of 10 miles per hour, hence in 5 hours, he can cycle a total distance of 50 miles.

Step-by-step explanation:

The question asks us to calculate how many miles Dewey can ride his bicycle in 5 hours based on his current rate of speed. Dewey rides 2 miles in 0.20 of an hour, so to find out how many miles he can cover in one hour, we divide the number of miles by the fraction of the hour ridden:

1. First, calculate Dewey's speed per hour: 2 miles ÷ 0.20 hour = 10 miles per hour.
2. Next, determine how far he can ride in 5 hours at that speed: 10 miles/hour × 5 hours = 50 miles.

Therefore, Dewey can ride 50 miles in 5 hours.
