Answer:

2. 20 km at 60 mph will take 12 minutes and 48 seconds

3. 228 km

Explanation:

Times mo lang ung 76 km/h sa 3h

Ang makukuha ay 228 km

4. Distance = 60 kilometres

Given

Speed of the train = 90km/hr

Time = 40 minutes

For calculating distance we need to convert time in minutes to time in hours

So,

40 minutes = 40/60hours

Simplifying

40/60 = 20/30

20/30 hours = 2/3 hours

Distance = speed × time

Distance = 90 × 2/3

Distance = 30 × 2

Distance = 60 kilometres

The train will travel 60 kilometres with a constant speed of 90 km/hr in 40 minutes

5. 20 km in 5 hours,

Explanation:

you can solve it by multiplying 84 by 5...it is because in one hour,it can travel 84 km...when you multiply it by 5 hours then the equation would be, 84x5=420 km...but don't forget to label the answer first or else the answer would be incorrect.So label it with km in 5 hours so the answer is, 420 km in 5 hours..
