Abike race is 50 miles long. if each lap is 10 miles and 4 laps have already been completed, how many more laps are left in the race?

You know that the total race is 50 miles. If each lap is 10 miles and 4 laps have already been completed, there would be one lap left.

This is because of the following,

10x4 = 40

50-40 = 10

1 lap= 10 miles

If a bike race is 50 miles long, and each lap is 10 miles, then we will count by tens per lap.  So if 4 laps have already been completed, we take 10 x 4 to get 40.  If each lap is 10 miles long, then all we need is 1 more lap to get to 50.  So your answer would be 1 lap is left.  Hope this helped!

step-by-step explanation:

y=mx+b

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
