The lopez family is traveling from the beach to their house at a average speed of 65 miles per hour. at noon, they have driven 50 miles. which equation represents the total distance they have driven, d, in terms of the number of hours since noon, h?

To solve the question we use the formula for distance given by:
speed=distance/ time
thus
distance=speed×time
hence given that:
speed=65 miles per hour
time=h
distance, d=50 miles
plugging the values we shall have:
d=65×h
d=65h
but d=50 miles
thus
50=65h
Hence the expression is:
50=65h
