Speed of object is 80 km/hr

Step-by-step explanation:

Step 1: Formula for Speed = Distance/Time

Given Distance = 120 km and Time = 90 min

Step 2: Convert given data into SI units.

Time = 90 min = 90/60 hours = 3/2 = 1.5 hours

Step 3: Substitute in the formula

Speed = 120 km /1.5 hrs

= 1200/15 = 80 km/hr
