Question

At the speed of 18 km/h, a cyclist cover a distance in 190 minutes. at what speed can he cover the same distance in 3 hours?​

Answer 1

Speed = 18km/h = 300 metre / minute

Time = 190 mins

Then, Distance = Speed × Time

= 300 × 190 metre

= 67000 metre

=67 km

Now, Time = 3 hours

Distance = 67 km

Speed = Distance / Time

= 67 km / 3 hours

= 22.3 km/ h

Answer 2

Answer:

Step-by-step explanation:

this is inverse proportional. he has to be more faster to cover the same distance in 180 mins.

Speed=distance/time

18km/hr = d/190min

18km/hr=d/3.16hr

d=18km/hr *3.16hr=56.88km

if he covers the same distance in 3 hours or 180 mins then speed  should be

speed= distance/time

speed=56.88km/3hr

speed=18.96km/hr
