Laisha rides a bike 8 miles in 40 minutes. Jefford rides a bike 5 miles in 30 minutes.
Who will bike the farthest in 1 hour?

2nd question- how much farther?

Step by step explain

Answer 1

We know that 1 hour = 60 minutes.

Set equal proportions for both Laisha and Jefford to find the distance x and y they bike in 60 minutes:

• Laisha 8/40 = x/60 ⇒ 1/5 = x/60 ⇒ x = 60/5 = 12 miles
• Jefford 5/30 = y/60 ⇒ 1/6 = y/60 ⇒ y = 60/6 = 10 miles

Laisha will bike farther by:

• 12 - 10 = 2 miles
