Explanation:
Detailed explanation-1: -That is speed = distance ÷ time. Or to put it another way distance divided by speed will give you the time. Provided you know two of the inputs you can work out the third. For example if a car travels for 2 hours and covers 120 miles we can work out speed as 120 ÷ 2 = 60 miles per hour.
Detailed explanation-2: -To solve for distance use the formula for distance d = st, or distance equals speed times time. Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t.
