Transcript

Example 8 (Time and Distance)Ajit can ride a scooter constantly at a speed of 30km/hour. Draw a time-distance graph for this situation. Use it to find.(i) the time taken by Ajit to ride 75km. (ii) the distance covered by Ajit in 3 1/2 hours.Given, Speed of scooter = 30kms/hour The formula for distance is Distance = Speed × Time We need to make a time-distance graph So, finding different values of Distance at different values of time Example 8 (Time and Distance)Ajit can ride a scooter constantly at a speed of 30km/hour. Draw a time-distance graph for this situation. Use it to find.Given, Speed of scooter = 30kms/hour The formula for distance is Distance = Speed × Time We need to make a time-distance graph So, finding different values of Distance at different values of time Example 8 (Time and Distance)(i) the time taken by Ajit to ride 75km.  So, the time taken by Ajit to ride 75km is 2.5 hours Example 8 (Time and Distance)(ii) the distance covered by Ajit in 3 1/2 hours. So, the distance covered by Ajit in 3 1/2 hours is 105 km
