Question

tony rollerbladed 4 miles in 20 minutes. what was his speed in miles per hour ?

Answer 1

Distance = 4 Miles.
Time = 20 min
We need to convert it in hours.
1 hour = 60 min.
So, 20 min = 20/60 hours = 1/3 hours.
Speed = Distance / Time.
Speed = 4÷ (1/3)
Speed = 4×3
Speed = 12 Miles per hour

Answer 2

Distance = 4 miles
Time = 20 minutes
So , in one hour -
Time = 20×3 minutes
= 60 minutes
= 1 hour
Distance = 4×3
= 12 miles

Speed = Distance/Time
= 12miles/hr
