Question

Write an algebriac expression using speed and time to calculate the distance,
simple interest to be paid, using principal, time, and the rate of simple interest
​

Answer 1

• You can use the equivalent formula d = rt which means distance equals rate times time. To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
• Simple Interest Calculation
• Simple Interest is calculated on the principal amount on a daily/monthly/annual basis. Principal Amount remains constant during the entire tenure on Simple Interest. The formula for calculating Simple Interest is P x r x t ÷ 100, where P=Principal Amount, Rate of Interest & T= Time.
