Question

square root B-2C express in words

Answer 1

Key Strategy in Solving Quadratic Equations using the Square Root Method. The general approach is to collect all x2 terms on one side of the equation while keeping the constants to the opposite side. After doing so, the next obvious step is to take the square roots of both sides to solve for the value of x.

Given,

The length of the race = 500 metres

The speed of the athlete = 50 km/h

To find,

The time taken by that athelete to complete the race.

Solution,

We can solve this problem by using the normal arithmetical method.

So,

The athelete runs 50 km in = 1 hour

The athelete runs 50000 m in = 3600 seconds

The athlete runs 1 m in = 3600/50000 seconds

The athelete runs 500 m in = 500×3600/50000 = 36 seconds

Hence,the athelete will take 36 seconds to complete the race.
