Final answer:
Calculating Eldo's average speed as 7.5 miles per hour, by dividing 15 miles by 2 hours, and then multiplying this by 7 hours, shows that Eldo can ride a total of 52.5 miles in 7 hours.
Step-by-step explanation:
If Eldo can ride his bike 15 miles in 2 hours, we can calculate how many miles he can ride in 7 hours by first determining his average speed and then multiplying it by 7 hours.
Step-by-Step Explanation:
Find Eldo's average speed by dividing the total miles he can ride by the total hours. Average speed = 15 miles / 2 hours = 7.5 miles/hour.
Multiply Eldo's average speed by the number of hours in question. 7.5 miles/hour * 7 hours = 52.5 miles.
Ergo, Eldo can ride 52.5 miles in 7 hours.
