Answer:
the distance covered is 11.25 km
Step-by-step explanation:
Given that
The speed of the bicycle is 15 km/h
And, the time taken of the bicycle is 45 minutes
We need to determine the distance covered
As we know that
Speed = Distance ÷ Time
So, distance = Speed × time
= 15 km /h × 0.75 hours
= 11.25 km
The 0.75 hours come from
= 45 minutes ÷ 60 minutes
= 0.75 hours
Hence, the distance covered is 11.25 km
9 + t/12 = -3
t/12 = -12
t = -144
hope this helps
