Keshia ran 10 1/2 miles in 1 3/4 hours. Mateo ran 12 miles in 2 2/5 hours. Who ran faster

Answer 1

To figure out who ran faster, we need to compare their speeds. Speed is calculated by dividing the distance traveled by the time taken.

Keshia's speed is calculated as 10 1/2 miles / 1 3/4 hours:
= (21/2) miles / (7/4) hours
= (21/2) * (4/7) miles/hour
= 42/7 miles/hour
= 6 miles/hour

Mateo's speed is calculated as 12 miles / 2 2/5 hours:
= 12 miles / (12/5) hours
= 12 * (5/12) miles/hour
= 5 miles/hour

Comparing the speeds, we can see that Keshia ran faster than Mateo.
