Sam's rate = 10.32 miles per hour
Step-by-step explanation:
distance = 63756ft
time = 70 minutes
if 5280 feet = 1 mile
let the number of mile of 63756ft = y
5280 feet = 1 mile
63756 feet = y
cross multiply:
y (5280) = 1(63756)
5280y = 63756
y = 63756/5280
y = 12.075 miles
time in minutes = 70 minutes
let the time in hour = x
60 minutes = 1 hour
70 minutes = x
cross multiply:
x(60) = 1(70)
60x = 70
x = 70/60
x = 1.17 hour
Rate = distance/time
Rate in miles per hour = 12.075 miles/1.17 hour
Rate = 10.32 miles per hour
