Question :    Find the distance covered by a scooty in 22 hours if it covers a distance of 98 km in 12 hours.

Correct Answer  179.74 km

Solution & Explanation

Solution

Given,

Distance = 98 km

Time = 12 hour

Thus, distance covers in 22 hour = ?

Here the speed and time are given. So, we need to find the speed to calculate the distance covers in the given time.

Method (1) Using Formula

Calculation of Speed using formula

Formula to find the speed

Speed = ^Distance/_Time

= ⁹⁸/₁₂ = 8.17 km/h

Thus, speed = 8.17 km/h

Calculation of the distance in the given time using formula

Formula to find the distance

Distance = Speed × Time

= 8.17 km/h × 22 hour = 179.74 km

Thus, the distance covered in the given time = 179.74 km Answer

Method (2) Using Unitary Method

Calculation of the Distance using formula

Given,

Distance = 98 km

Time = 12 hour

Thus, distance covers in 22 hour = ?

∵ In 12 hours the distance covered = 98 km

∴ In 1 hour the distance covered = ⁹⁸/₁₂ km

∴ In 22 hours the distance covered

= ⁹⁸/₁₂ × 22 km

= ^{98 × 22}/₁₂ km

= ²¹⁵⁶/₁₂ = 179.74 km

Thus, the distance covered in the given time = 179.74 km Answer
