Question

Mr. Pilot always rides his bicycle to work,

and he begins his ride at the same time every
day. If he averages 10 miles per hour, he
arrives at school 2 minutes late, but, if he
averages 15 miles per hour, he arrives 1
minute early. How many miles does Mr.
Pilot ride to work? Express your answer as a
lecimal to the nearest tenth.

Answer 1

what's a lecimal?

Explanation:

Answer 2

Answer:same,If he average speed is 10 miles per hour (1/6 miles per minute),he need 7+2=9 minute to arrive at work.

9*(1/6)=3/2 miles=1.5 miles

Step-by-step explanation: 10 miles per hours =1/6 miles per minute

15 miles per hours=1/4 miles per minute

Now, assume he need x minute to rides his bicycle to work.

if he averages 10 miles per hour ,then he need (x+2) minute to arrives at work

if he averages 15 miles per hour,then he need (x-1)minute to arrives at work

distance equal velocity multiply by time. d=v*t

distance did not change,so we can set up an equation like....

1/6*(x+2)=1/4*(x-1)

x+2=1.5(x-1)

x+2=1.5x-1.5

0.5x=3.5

x=7

If if he average speed is 15 miles per hour (1/4 miles per minute), he need 7-1=6 minute to arrive at work

6*(1/4)=3/2 miles=1.5 miles
