Quincy rides his bicycle 1 mile in 4 minutes, and his sister Marissa runs 13,376 feet in 16 minutes. In miles per hour, approximately how much faster is Quincy than Marissa? (Note: 1 mile = 5, 280 feet) 5.5 miles per hour 7.5 miles per hour 9.5 miles per hour 17.0 miles per hour

5.5 miles per hour

Step-by-step explanation:

Quincy rides his bicycle 1 mile in 4 minutes, and his sister Marissa runs 13,376 feet in 16 minutes.

We have to convert 13,376 feet to miles first. We should note that 1 mile = 5280 feet. Therefore 13,376 feet will be:

= 13376/5280

= 2.533 miles

We can then rewrite as:

Quincy rides his bicycle 1 mile in 4 minutes.

Marissa runs 2.533 miles in 16 minutes.

Since Quincy rides his bicycle 1 mile in 4 minutes, in an hour, he'll have rode the bicycle for:

= 60 minutes/ 4 minutes

= 15 miles in 1 hour

Since Marissa runs 2.533 miles in 16 minutes,.in an hour,. she'll have run for:

= 2.533 × 60/16

= 9.5 miles in 1 hour.

Note that: 60 minutes = 1 hour

In miles per hour, approximately how much faster is Quincy than Marissa?

To solve the question, we've talked find the difference between both and this will be:

= 15 miles - 9.5 miles

= 5.5 miles per hour
