When time in hours (t) increases, how does distance in km (d) change?

Question seems incomplete but will be explained with assumptions

Answer and explanation:

If for example, a car travels 30 km per hour, then it would travel 60km in 2 hours and 90km in 3 hours and so on

We can apply the formula for distance as such:

Distance(d)= Speed(s) × time(t)

d=st

Where d is distance travelled say 60km

S is speed= 30km/hr

Time = 2 hrs

Also to calculate speed when distance and time is given, we can make speed the subject of the formula:

s=d/t

To calculate time when distance and speed are given, we can make time the subject of the formula:

t=d/s
