• D. Bike B that travels 288 miles in 8 hours

Answer 1

The correct option is D Bike B that travels 288 miles in 8 hours

A.
Bike A that travels $270$ miles in $6$ hours

Speed of Bike A $=\frac{\text{Distance covered}}{\text{Time taken}}=\frac{270}{6}=45$ miles per hour

B.
Bike A that travels $288$ miles in $8$ hours

Speed of Bike B $=\frac{\text{Distance covered}}{\text{Time taken}}=\frac{288}{8}=36$ miles per hour

C.
Bike A that travels $322$ miles in $7$ hours

Speed of Bike C $=\frac{\text{Distance covered}}{\text{Time taken}}=\frac{322}{7}=46$ miles per hour

D.
Bike A that travels $400$ miles in $10$ hours

Speed of Bike D $=\frac{\text{Distance covered}}{\text{Time taken}}=\frac{400}{10}=40$ miles per hour

So, Bike B has the lowest speed.
