Question

a car travels 2 5/8 miles in 3 and 1/2 minutes at a constant speed what equation can represent to the distance D that the car travels in M minutes

Answer 1

Given that Distance = 2 5/8 miles = 21/8 miles

Time = 3 and 1/2 minutes = 7/2 minutes

Then speed of the car is given by formula :
`Speed=(Distance)/(time)=((21)/(8))/((7)/(2))=(21)/(8)*(2)/(7)=(42)/(56)=(3)/(4)`

miles per minute

Hence distance travelled in M minutes will be given by equation

`D=(3)/(4)M`
