Question

PLEASE HELP ME I'M STUCK ON THIS QUESTION!!!!!!!!!!!!!!!!!!!!!!

Grant can row 6 miles in 36 minutes. Arianna can row 3,520 yards in 20 minutes. In miles per hour, how much faster does Grant row than Arianna? (Note: 1 mile = 1, 760 yard)

Answer 1

We wish to know how much faster Grant rows than Arianna.

d=G-A and we want our answer is miles/hour so

d=(6mi/36min)(60min/hr)-(3520yd/20min)(mi/1760yd)(60min/hr)

d=10mph-6mph

d=4mph

So Grant rows 4 miles per hour faster than Arianna.
