Question

An albatross is a large bird that can fly 400 kilometers in 8 hours at a constant speed. Using d for distance in kilometers and t for number of hours, an equation that represents this situation is d=50t. Write another equation for d and t in this context

Answer 1

Explanation:

The formula for calculating speed is expressed as;

Speed v = distance d/time t

v = d/t

Given

Distance = 400km

time = 8hours

Substituting into the formula

v = 400/8

Cross multiply

8v = 400

v = 50m/s

Substitute v= 50 back into the formula

v = d/t

50 = d/t

Cross multiply

50t = d

Rearrange

d = 50t
