Formulas: Distance, Rate & Time — Easy Worksheet 1

Solve each problem.

How to solve

Use d = r × t. To find distance, multiply rate by time; to find rate, r = d ÷ t; to find time, t = d ÷ r. For perimeter P = 2l + 2w, subtract the known doubled side from P and divide by 2, for example l = (P - 2w) ÷ 2.

Example

Using d = rt, find the distance d when r = 23 and t = 4.

Answer: 92

right so far
1 Using d = rt, find the distance d when r = 24 and t = 2.
2 Using d = rt, find the rate r when d = 48 and t = 4.
3 Using d = rt, find the time t when d = 51 and r = 17.
4 The formula for perimeter is P = 2l + 2w. Solve for l when P = 14 and w = 2.
5 Using d = rt, find the distance d when r = 2 and t = 2.
6 Using d = rt, find the rate r when d = 36 and t = 4.
7 Using d = rt, find the time t when d = 32 and r = 8.
8 The formula for perimeter is P = 2l + 2w. Solve for w when P = 16 and l = 6.
