Question

Nora bikes 30 miles per hour. Jiro bikes 45miles per hour. If nora and jiro each bike for 2 hour, how many more miles does jiro bike

Answer 1

75 is your answer, hope i can help you

Answer 2

If Nora bikes 30 miles per 1 hour, she'll ride 5 times as much in 5 hours.
30*5=150 miles
Jiro at 45 miles per 1 hour
45*5=225 miles in 5 hours

To find out how many more miles Jiro rides than Nora, subtract:
225-150=75
