Question

A person walks at the rate of 4 km/hr . How long will he take to go round a square park 5 times, whose area is 2500 m² ?

Answer 1

Answer:

0.25 HR = 15 min

Step-by-step explanation:

Area of Square park = 2500 m²

Side of park = √2500 = 50 m

Distance to cover one round around park = 4 X Side of park = 4 X 50 =200 m

Total distance to be covered = 5 times around park = 5 X 200m = 1000m = 1 Km

Time = distance/ speed

= 1/4 = 0.25 HR = 15 minutes

Answer 2

Answer:

3 hr 7.5 min

Step-by-step explanation:

Time = Distance/Time
