To write this as an algebraic expression, remember that twice a number means that 2 is being multiplied by a number. Since we are not solving, we can just use the variable n to represent the number that is being multiplied by 2. Finally, adding 5 to the number we will get the expression 2n + 5.
Answer:
48 km/h
Step-by-step explanation:
Distance = 120 km
Time = 2½ h
Speed = ?
We know that
Speed = Distance/Speed
Let,
Speed = v km/h
=> v = 120/(2½)
=> v = 120/(5/2)
=> v = 120 × 2/5
=> v = 24 × 2
=> v = 48 km/h
Average speed is 48 km/h
